The Complete Javascript Course 2020 Build Real Projects [extra | Quality]

The Complete JavaScript Course 2020: Build Real Projects, created by Jonas Schmedtmann, is widely considered one of the most comprehensive and high-quality resources for learning JavaScript. Though originally titled for 2020, the course is frequently updated to reflect the modern ecosystem, covering everything from basic syntax to complex architectural patterns. Core Philosophy The course follows a "learning by doing" approach. It moves away from isolated code snippets and focuses on building large-scale applications. This helps students understand how different parts of the language—like the DOM, asynchronous logic, and state management—work together in a professional environment. Key Learning Pillars The Fundamentals: A deep dive into variables, data types, operators, and control structures. Behind the Scenes: Unique modules explaining how JavaScript actually works (the engine, execution context, scoping, and hoisting). Modern ES6+: Extensive coverage of arrow functions, destructuring, the spread operator, and template literals. Asynchronous JS: Mastering Promises, Async/Await, and AJAX to fetch data from APIs. Object-Oriented Programming: Understanding prototypes, classes, and inheritance. Major Projects Included Pig Game: A simple logic-based game to practice DOM manipulation and state variables. Mapty App: A workout tracking app using geolocation and the Leaflet library to map user data. Forkify: A massive recipe application featuring a custom search, servings adjustments, and a "bookmarking" system. This project introduces the Model-View-Controller (MVC) architecture. Why It Stands Out Visual Aids: Schmedtmann uses high-quality diagrams to explain abstract concepts like the "Temporal Dead Zone" or the "Event Loop." Tooling: It teaches modern workflows, including NPM, Webpack, Parcel, and Babel, rather than just writing code in a single HTML file. Problem Solving: Each section includes coding challenges to test retention and logical thinking. No Framework Reliance: It focuses on "Vanilla" JavaScript. This ensures students build a strong foundation before moving on to React, Vue, or Angular. Target Audience The course is designed for absolute beginners who have never coded, as well as intermediate developers who know some JavaScript but feel they lack a "deep" understanding of how the language operates under the hood. If you are planning to take this course, I can help you prepare a study schedule or explain specific concepts. Let me know: What is your

The Architecture of Logic: A Meditation on "The Complete JavaScript Course 2020" To look back at "The Complete JavaScript Course 2020" is to examine a time capsule of digital ambition. It was a course taught by the ever-methodical Jonas Schmedtmann, a voice that guided thousands through the chaotic adolescence of the web. But to view it merely as a series of syntax tutorials is to miss the profound philosophical shift it represents—a transition from the static, document-based internet of the past to the dynamic, application-based world of the present. This was not just a course on how to write code; it was a course on how to think in the language of the browser. The Death of the Static Page The course begins in the shallows—variables, data types, operators—but quickly pulls the student into the deep waters of DOM Manipulation . This is where the magic happens. Before this moment, the web is a museum: paintings on a wall, unchanging and distant. JavaScript, as taught in these early sections, is the act of bringing the museum to life. It is the realization that the elements on the screen are not fixed entities but malleable objects that can be summoned, altered, or erased with a single command. The "Budget App" or the "Pig Game" projects are not just exercises in logic; they are the student's first act of godhood over the digital void. You learn that the <div> is not a container of text, but a living node in a tree that breathes with user interaction. The Complexity of Asynchronicity The true depth of the course, however, lies in its treatment of Asynchronous JavaScript —the Promises, the Async/Await syntax, and the Event Loop. This is the moment where the student's linear, human perception of time clashes with the machine’s disjointed reality. Understanding a Promise is understanding that the computer does not wait. In the real world, if you order a coffee, you wait for the coffee. In the JavaScript event loop, you order the coffee and immediately start answering emails while the barista works. The course forces the student to grapple with the anxiety of pending states. It teaches you to write code that is resilient to uncertainty, a skill that translates far beyond programming: How do you proceed when the data has not yet arrived? The sections on fetch and AJAX are particularly poignant. They expose the internet as a series of conversations. The browser is no longer a passive viewer but an active participant, reaching out across the network to APIs, shaking hands with servers, and bringing back resources to build the experience. It is a lesson in connectivity and dependency. The Blueprint and the Concrete Perhaps the most enduring legacy of the 2020 edition is its heavy focus on Object-Oriented Programming (OOP) and ES6 Classes . This is where the abstract becomes concrete. The course moves from writing loose scripts—spaghetti code that tangles and trips—to building architecture. When you build the "Mapty" workout application, you are not just typing; you are designing a taxonomy. You create a Running class and a Cycling class. You define what they are and what they do . This is the fundamental shift from a coder to an engineer. A coder writes instructions; an engineer designs systems. The course demands that you think about inheritance, encapsulation, and abstraction. You learn that a well-structured class is a form of empathy—it makes the code readable for the next person, including your future self. The Eternal Framework vs. The Vanilla Core In 2020, the landscape was dominated by React, Vue, and Angular. Students often rushed to learn the frameworks, hungry for employment. But this course held a contrarian, almost stoic line: Master Vanilla JavaScript first. This was the deepest lesson of all. Frameworks are the changing fashions of the tech industry; they rise and fall with the seasons. But the underlying principles—prototypal inheritance, closures, the this keyword, scope chains—are the anatomy of the language. By forcing the student to build complex projects without the crutch of a framework, the course imparted a resilience. It taught that to understand the abstraction, you must first master the concrete. Conclusion: The Builder’s Mindset "The Complete JavaScript Course 2020" was ultimately about the psychology of creation. It took the amorphous anxiety of "I want to build an app" and broke it down into a series of solvable problems. It taught that bugs are not failures, but puzzles. It taught that error messages are not scolding reprimands, but maps pointing toward the solution. And it taught that the blank script.js file is not a terrifying void, but a canvas waiting for logic. To complete it was to cross a threshold. You did not just learn JavaScript; you learned the architecture of modern thought, translated into the syntax of the web.
